A barrel in the form of a frustum of a cone with a radius of 3m at the top and 6m at the bottom. It is 5m high and is 4/5 full of oil (0.85). Determine the: a. Total hydrostatic force acting on the wall of the barrel in kN  b. its line of action from the bottom

The spring is placed between the wall and the 11.5-kg block. If the block is subjected to a force of F = 570 N, determine its velocity in m/s when s = 0.5 m. When s = 0, the block is at rest and the spring is uncompressed. The contact surface is smooth. k = 510 N/m %D k :

20 kN/m ↓↓ 4 m 3 m 2 m 30 kN a 1.5a A beam is supported by a column 3 m tall with dimensions a x 1.5a as shown above. The column is fixed at the base and pinned to the beam. Assume a Young's modulus of E = 25 GPa and yield strength of σ,, = 20 MPa for the column. a) Draw the SFD and BMD for the beam and determine the axial load acting on the column. b) What is the minimum value of "a" that would not result in buckling of the column? c) If the column was instead fixed to the beam, how would this change the minimum value of "a"?

26. Determine the force F required to keep the 200 kg crate in equilibrium with the position shown.
